CENTRIFUGAL LOTHES DRIER FOR WASHING MACHINES `Filed Jan. 2o, 19:50 2 sheetssheet 2 Patented Oct. 13, 1931 UNITED STATES PATENTv Voi-Fici-zA Application illed January 20, 1980. Serial No. 422,178.

This invention relates to centrifugal clothes driers for washing machines, and an object of the invention is to provide a means p for introducing water during the drying op; eration, so as to eliminate the removal o the clothing from the drying compartment for rinsing the clothes.

Another' feature of the present invention is to provide for equal distribution of the 1o rinse water thru all of the clothin in the dryin compartment, and to furt ermore provi e for aerating the clothing during the rinsing operation by utihzmg the vacuum or suction created by withdrawing the rinse l5 water.

Another feature of the invention is to provide for causin the clothes to be equally divided in the rying compartment, thereby reducing vibration of the drier to a. minimum.

With the foregoing and other obiects in view, the invention consists of a novel construction, combination and arrangement of parts as will be hereinafter more specifically described and illustrated in'the accompanying drawin s, wherein is disclosedan embodiment 0% the invention, but it is to be understood that` changes, variations, and modifications, may be resorted to without departin from the spirit of the claim hereto ap en ed.

n the drawings, wherein like reference characters denote corresponding parts throughout the several views Figure 1 is a fragmentary section vertical in detail throu h a portion of al washin machine illustrating the improved centri ugal l clothes drier assembled therewith,

Fig. 2 is a fragmentary, top plan viewl thereof.

Fi 3 is a horizontal section taken substantially on the line 3-3 of Fig. 1, and looking in the direction of the arrows.

Referring to the drawings in detail, 4 indicates an offset portion of a conventional washing machine that is adapted to be equipped with the centrifugal drier in accordance with the present invention.

Numeral 5 indicates the top wall of the washer and 6 indicates the bottom Wall thereof. Formed between the top and bottom wall of the washer 4 is a circular comartment or container 7 formed by a vertically disposed circular wall 8 that is secured in any conventional manner to the top and bottom walls. The drying compartment 7 is open at its top and is closed by a hinged cover 9. The cover 9 is stationary and removably supported on the top wall 5 by means of turn buckle 1() mounted on the to wall 5, the inner ends of which are adeptes to overhang the fiange 11 about the perimeter of the cover 9.

A'depending apertured collar 12 is formed in the center of the bottom wall 13 of compartment 7 to form a bearing for the drive shaft 14 that extends therethrough. The drive shaft may be connected with any suitable driving mechanism not shown in the drawings.

The rotatable drying chamber indicated generally at 15 consists of a vertically disposed, hollow, cylindrical container in the form of a basket 16, open at its top and having its bottom wall 17 resting on a disk 18 secured to the inner end of drive shaft 14 by a nut 19 that threadably engages about the inner end of said drive shaft.

In the center of the bottom wall 17 is a socket 20 which is counter-sunk with res ect thereto in which the nut 19 is seated. ottom wall 17 is imperforate, but the side wall is formed with vertically spaced, staggered openings 21. The openings 21 are coextensive with the side walls. A cover 22 for drying chamber 15 is formed with a beveled flange 23 depending from its outer periphery that rests upon the upper rolled edge 24 ofthe chamber.

The cover 22 is adapted, in a manner to be presentedly described, to rotate with the drying chamber 15. The cover 22 is spaced below the cover 9, the bottom wall 17 of container 16 is spaced from the bottom wall of compartment 7, and the side Walls of the chamber 15 are spaced from the walls 8 of compartment 7.

Furthermore, container 16 is disposed concentric with respect to the walls of the .con-

tainer. Rising from the bottom wall 17 of the bottom wall 17 in any conventional manner. The bottom of the tubular member 25 is closed, bythe wall 26 and is open at its to %`he side wall of the tubular member 25 is formed with staggered openings 27 throughout its entire length and the number of openings formed in the guide walls progressively increase from the bottom to the top thereof. The tubular member 25 is materially less in diameter than Ithe container 16, and this tubular member 25 terminates slightly below the upper edge of the drying chamber. 4

A bearing housing 29 is secured lby means of screws 30 to the outer face of the stationary cover 9 at the center thereof. Depending from the center of the bearing plate is an open conductor pipe 31 that provides an inlet into the tubular member 25 and is to receive the discharge end of a hose not shown in the drawings. The top of the housing is provided with a central opening communicating with the pipe 31.

Supported in a pocket 32 formed inthe side wall of the bearing housing 29 is a stationary, vertically disposed ball race 33. The stationary cover plate 9 and the cover 22 that rotates with the drying chamber 15, are formed with registering openings, and the opening 34 in cover 9 is larger than the openings in cover 22.

Extending through these openings in covers 9 and 22 is a sleeve 35 threaded on its outer face, adjacent the upper and lower ends thereof. The inner face of the sleeve 35 is spaced from the conductor pipe 31 which extends through its axis. A nut 36 threadably engages with the threaded upper portion of sleeve 35 and rigidly secures a rotating ball race 37 disposed about a plain portion of the sleeve. The lower end of the ball race 37 bears on the upper end of a tubular collar 38 that is disposed about the sleeve 35, and the lower end of this collar rests upon the upper face of cover 22 about the opening therein.

The collar 38 is disposed in spaced relation to the walls of the openings 34, so that it will not rub the walls of the opening, when it rotates with the sleeve 35. A tubular nut 39 threadably engages the threaded lower portion of sleeve 35 and has depending, inwardly flared portion 4() that is received in the upper end of the tubular member 25.

Ball bearings 41 are disposed between ball races 37 and 33 to form a bearing between the stationary cover 9 and the rotating cover 22. From the foregoing description, it will be apparent that the axial disposition of tubular member 25 prevents clothes from being fed into the rotating) dryingchamber 15 in an yuneven manner, ut requires the clothes to be clearly packed about this tubular member, all of which goes to require even distribution of the weight of the clothes to eliminate vibration and the moving parts.

The progressive increase in the number of openings from the bottom to the to of tubular member 25, provides an yequa flow of water throughout the entire length of the `tube, the increase in number of openings compensating for the increased pressure at the bottom of the tube, due to the weight of the column of water therein.

When the clothes are packed in drying compartment 15, a hose introduced into conductor pipe 31 will introduce water from a remote source, either'hot or cold, as the drying compartment 15 is rotated. The ilow of water through tubular member 25 and the openings 21 in chamber 15, provides for a continuous rinsing of the clothes and the drying thereof in a single operation.

When the clothes in the chamber 15 have become rinsedA properly the influent water may be cut off. A suitable drain conductor 41 connected through the bottom wall 13 of chamber 7 leads to any conventional type of pump not shown in the drawings, to carry olf rinse water that collects in the bottom of compartment 7. As the rinse water is pumped out of compartment 7, the air that displaced the water will aerate the clothing in chamber 15.

It is to be understood that by describing in detail herein a particular form, structure or arrangement, it is not intended to limit the invention beyond the terms of the claim, or the requirements of the prior art. v

Having' thus described my invention, what l claim as new is A centrifugal clothes drier for washing machines comprising a fixed open top con-- tainer, a perforated open top basket mounted for rotation in the container, an upstanding, perforated tube xed centrally in the basket and having an open upper end adjacent the top of the basket, a stationary cover for the container having a centrally disposed opening therein, an upstanding housing mounted on the cover having a central opening in its top disposed coaxially with the cover opening, a stationary tube formed integrally with the housing and depending therefrom through the cover opening in spaced, concentric relation thereto, a rotatable tube encircling the stationary tube and extending through the cover opening in spaced, concentric relation thereto into the housing and having externally threaded upper and lower portions, a collar mounted on an intermediate portion of the rotatable tube, a. bearing mounted in the housing and encircling the rotatable tube and engaged with the collar, a nut threaded on the upper portion of the rotatable tube and engaged with the bearing and, in conjunction with the collar, constituting means for connecting the rotatable tube with the bearing, said bearing constituting means for rotatably mounting the rotatable tube on the cover, a basket cover mounted on the rotatable tube and engaged on the basket for rotation therewith, said basket cover being engaged with the collar, and a nut threaded on the lower portion of the rotatable tube and engaged with the basket cover, said nut having a tapered extension depending below the rotatable tube and engageable with the upper end of the perforated tube.

In testimony whereof I affix my signature.
